Abstract
A brake stroke sensor and an steering sensor are individually and collectively provided. A brake stroke sensor includes a force-receiving plate, a second plate movable relative to the force-receiving plate, a spring disposed between the plates and operatively connected to the pushrod, a strain gauge bridge mounted on the force-receiving plate and a microcontroller capable of converting the strain gauge bridge signal into digital data. A steering sensor includes a mechanical interface operatively connected to a nonmoving member and a moving member, an encoder capable of transforming the rotational motion of the mechanical interface into an electrical signal, and a microcontroller capable of calculating, from the electrical signal, a count indicative of the relative positions of the members. A combined brake stroke and steering sensor may include individual and common elements of both the brake stroke and steering sensors described above. The brake stroke, steering sensor and combined brake stroke and steering sensor may utilize a modem for transmitting data to a system controller over an electrical bus.
